China DOS Union

Some netizens asked me how to install MS-DOS 7.10 to the hard disk after booting with the MS-DOS 7.10 boot disk. Therefore, I am going to make a full version installation program of MS-DOS 7.10 with batch processing + WBAT and some tools when I have time recently. Everyone is welcome to put forward opinions and suggestions. Thank you!

Why hasn't anyone replied? Then I'll just not do it.

I can only say this is a good thing! But rookies still hope to do it by themselves. Hope the boss gives more guidance...

To say making the MS-DOS 7.10 installation program itself, it might really be difficult for rookies to do it, because it's not that easy to make, because it involves relatively more knowledge. But using the already made installation program to install MS-DOS 7.10 on the hard disk is something everyone can do.

I studied your program today and was startled. I sincerely admire you.

You're welcome. Can everyone come up with some suggestions regarding the creation of the MS-DOS 7.10 installation program?

Just like DOS 6.22!

I have carefully considered it. Besides the interface and others, some steps are still quite complicated. For example, for the "conduction system" item, at least the following judgments need to be made:

1: Whether WinNT/2K/XP has been installed on the hard disk. If yes, automatically make a dual boot of DOS and WinNT/2K/XP;
2: Whether DOS has been installed on the hard disk. If yes, need to automatically back up system files;
3: Whether the C drive is the primary boot partition and whether it can boot. If not, it is also necessary to continue to judge and perform operations such as activating the partition;
4: Whether the CPU is 386 or above? Whether the memory is too little? Whether the hard disk space is sufficient?
5: Need to automatically configure, especially to automatically set files such as MSDOS.SYS according to the situation of this system.

In short, there are a lot of things to do. Especially the above third question. If anyone knows how to judge, please inform, thank you!

Can I not format the C drive during installation! I only have one C drive, can 6.22 and 7.10 coexist! Can make a dual boot! Thank you for the guidance!

Sure, if there is enough space and there are no FAT32 partitions/large hard disks or long filenames in the hard disk, you can use dual-booting. An important update of MS-DOS 7.10 is to support dual-booting.

Need to program for detection, right?

How to compile this? I don't know how to compile a program that performs low-level operations on the disk. Is there any ready-made detection software?

I remember that the bootable partition has a flag in the partition table, which seems to be the 55 AA flag.

But I'm not very familiar with this aspect. You should be able to contact the author of SPFDISK, he should be the most familiar with this aspect.

Mistaken, sorry. The 55 AA should be the partition end flag, and 80 is the bootable flag. But there are still offset positions in it. It's better to ask Feng Xuping (the author of SPFDISK).

Doing that installation program is not as good. Teach everyone how to use wbat. In this way, you can learn more useful things.
